Leaf springs are a type of suspension system commonly used in vehicles, especially trucks and trailers. They consist of several layers of metal strips, or leaves, that are stacked together. This design allows the spring to flex and absorb shocks from the road, providing a smoother ride and better load-carrying capacity. The primary function of leaf springs is to support the weight of the vehicle while maintaining stability. They help to distribute the load evenly across the axle, which is crucial for maintaining balance and control. Leaf springs are often found in conjunction with other suspension components, such as shock absorbers and coil springs, to enhance overall performance.
